The nominal voltage of a single cell is generally: 3.6V or 3.7V
The charging voltage is generally: 4.20V (4.2V-4.3V for lithium cobalt oxide)
The minimum discharge termination voltage is generally: 2.75V, lower than this voltage will easily lead to a serious drop in battery capacity or even scrap
Maximum charge termination voltage: 4.20V
Diametru: 18 ± 0.2mm
Height: 65±2.0mm
Capacity: above 1000mAh, the conventional capacity is 2200mAh-3200mAh, the 18650 battery capacity is the highest is LG, which can achieve 3600mAh, but the price is not low.
